Abstract

The invention provides a vertical water storage type electric water heater provided with an electric heating pipe with an electric heating wire in a nonmetal pipe. A shell of the electric heating pipe is made of a nonmetal material. According to the electric heating pipe with guiding-out bars (1) at one end or two ends, the electric heating wire (3) is installed in a straight nonmetal pipe (7) or a blind hole type nonmetal pipe (8), and the guiding-out bars (1) extend out of the pipe through nonmetal plugs (6). The electric heating wire (3) is drily burned in air in the nonmetal pipe (7) or (8). A breaker (12) is installed at the lower part of the open end of the straight nonmetal pipe (7) or the blind hole type nonmetal pipe (8), one end of the breaker is provided with two exposed and isolated metal wires, the other end of the breaker is connected to a control element of a control circuit board, and when two metal wires simultaneously meet water and become conducted, the control element is informed to disconnect a circuit.

Description

Vertical water storage type electric water heater equipped with the electrothermal tube for having heating wire in non-metallic pipe

Technical field

The present invention relates to vertical water storage type electric water heater, in relating generally to Water tank for electrical water heater, the immersion for being adopted There is the electrothermal tube of heating wire in non-metallic pipe in water.

Background technology

The electrothermal tube being currently used in electric heater, 100% is by technical standard JB/T4088-1999《Daily pipe Shape heating》Or JB/T2379-1993《Tubular metal electric heating element》The tubular electrothermal element of production, be " with metal tube as shell, heating alloy make heater, at one end or two ends have eduction rod, in metal tube It is interior to load closely knit magnesium oxide powder dielectric, to fix the element of heater；" existing commonly use Heating；This metal shell heating, is completely sunk in the water, after long-time use, meeting scaling, Heating efficiency is reduced, and corrosion punctures, and makes water powered, is world-famous puzzle.

The content of the invention

The purpose of the present invention is that existing vertical water storage type electric water heater is improved.

The present invention technical measures be the water tank of vertical water storage type electric water heater by metal or nonmetallic making, it is built-in Having has the electrothermal tube 11 of heating wire in non-metallic pipe：It is built with heating wire 3 in straight-through non-metallic pipe or shell 7 With magnesium oxide powder or air 4, and heating wire 3 is fixed in non-metallic pipe 7, is pacified at the two ends of heating wire Dress eduction rod 1 outside protruded tube, becomes non-metal shell electrothermal tube 11 by nonmetallic plug 6；Or one End seal is closed becomes blind hole non-metallic pipe or shell 8 built with heating wire 3 and magnesium oxide powder or air 4；In electricity Eduction rod 1 is installed at the two ends of heated filament 3, and heating wire 3 is bent to into U-shaped, makes two eduction rods 1 at one end, Outside by the protruded tube of nonmetallic plug 6, become non-metal shell electrothermal tube 11；The heating wire 3 is non- Dry combustion method in air in metal tube.

Simultaneously in straight-through non-metallic pipe 7 or the open end bottom of blind hole non-metallic pipe 8, equipped with breaker 12, institute Breaker is stated, is the control element that one end is two wires that are exposed and isolating, the other end and control board Connection, when two one metal wires run into water conducting simultaneously, notes that control element, disconnects circuit.

The non-metallic pipe 7 or 8, first-selected quartz glass tube, either blind hole pipe or straight pipe, internal electric heating Silk has one or more, is isolated with non-metallic insulation thing 10 between heating wire, prevents short circuit.

The invention has the beneficial effects as follows the vertical Water storing electric heating equipped with the electrothermal tube for having heating wire in non-metallic pipe Hydrophone, is immersed in water not scaling, and electrothermal tube never corrodes and punctures, and will not leak electricity.

Description of the drawings

Fig. 1 is that two ends have the electrothermal tube for having heating wire in the non-metallic pipe of eduction rod；

Fig. 2 to Fig. 4 is that one end has the electrothermal tube for having heating wire in the blind hole non-metallic pipe of eduction rod 1；

Fig. 5 to Fig. 7 is equipped with non-metallic pipe the vertical storage-type electric water heater structure of the electrothermal tube for having heating wire and shows It is intended to；

Specific embodiment

In accompanying drawing, eduction rod or claim terminal 1, sealing ring or high-temp glue 2, heating wire 3, magnesia powder or non- Outside metal-insulator thing or air 4, metal or non-metallic pipe 5, nonmetallic plug 6, straight-through non-metallic pipe or title Shell 7, blind hole non-metallic pipe claim in shell 8, heater 9, non-metallic insulation spacer 10, non-metallic pipe Have the electrothermal tube 11 of heating wire, breaker 12, metal or nonmetallic water tank 15, shell 16, blind flange 17, Mounting seat 18, friction top 19.

Fig. 1 to Fig. 4 is that one end or two ends of institute's dress in vertical water storage type electric water heater have the employing of eduction rod non- There is the electrothermal tube of heating wire in metal tube, there is nonmetallic plug 6 termination, and eduction rod 1 passes through the protruded tube of plug 6 Outward；There is 1 or more heating wire 3 in non-metal shell, have non-metallic insulation thing 10 to be separated by between heating wire From；In non-metal shell, there are magnesia powder or non-metallic insulation thing or air 4, it is straight that Fig. 4 heating wire is often enclosed Footpath it is larger press close to tube wall.

Due to heating wire 3 can dry combustion method in atmosphere, therefore can be directly installed in non-metal shell, if with oxidation When magnesium powder is filled, the position of heating wire will not move.

Fig. 5 to Fig. 7 is vertical electric water heater with water tank structure chart, water tank 15 built with electrothermal tube 11, outside it It is water, the shell of this electrothermal tube is made up of nonmetallic, there are heating wire and the isolation of water glass in inside, never ties Incrustation scale, never punctures, and Fig. 5 is single water tank, and Fig. 6, Fig. 7 are double water tanks.

To realize double insulation, can again arrange between metal or non-metal electric heating silk 3 and non-metallic pipe 7 or 8 One layer of non-metallic pipe.
